Fiber Bragg Grating sensor Package measuring strain of concrete structure

摘要

The present invention relates to a fiber Bragg grating strain sensor packages for concrete measures. The present invention is prevented by embedding a fiber grating sensor embedded in a groove formed on the patch cord to the outer peripheral surface of the support to ensure the damage to the optical fiber and the grid forming part of the installation in the concrete structure, and forming a spiral on the outer peripheral surface of the support to the fiber grating sensor package When bound to the reinforced assembly due to increased friction and cohesion reinforced, concrete during construction of the concrete is cured in a state that is introduced between the spiral ridge and valley portions are integrated with the concrete support of concrete fiber Bragg grating sensor package is modified to correspond exactly to the one to be modified will be able to reliably measure the deformation of the concrete structures. In addition, the nut tightening spiral soon as the ends of the support as well as the nut is secured to the spiral ends of the support by the resin for laying of buried fiber optic patch cord grating sensors embedded in the home and all you gay for concrete structures as well as enhance The optical fiber grating patch cord can be reliably prevented from falling off from the ends of the support, whereby one will be able to measure the deformation of the concrete structures more reliably. ;
